Abstract

Despite a long history, the implementation tradeoffs and value assessment criteria of active noise control (ANC) are not well established. With commercial heavy truck adaptive ANC controllers now available, there is a need for an understanding of the unique performance-to-cost ratio characteristics of these systems. Also, due to the specific spectral region that these systems are applicable to, studies of the physiological effects of broadband noise poorly represent the positive impact of ANC. This paper presents a collection of implementation tradeoff metrics unique to active noise control systems. In addition, evaluation issues and research are identified that will help to validate ANC benefits that are accepted, but insufficiently supported.
